Looks OK-ish - there's a missing '{' on the third line but apart from
that it should work fine as a class method.

You can simplify the if-block as below, which might save you as much
as a microsecond or two :-)
function countNested($array){
$total = 0;
foreach ($array as $value) {
$total += is_array($value) ? $this->countNested($value) : 1;
}
return $total;
}

Re: [PHP] counting nested array
OK this the little function i made to solve this..
[CODE]
function countNested($array){
foreach($array as $value){
if(is_array($value))
$total=$this->countNested($value)+$total;
}else{
$total=$total+1;
}
}
return $total;
}
[/CODE]
any optimizations are welcome

If I understand you correctly, you only want the leaves of your tree - in your example, that would be 20? I don't think there's a convenient builtin function that'll do it, but it's not hard to write your own: -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Not sure if there's a PHP native function for doing this, though. Perhaps someone else knows. If nothing else, try this way.

[PHP] counting nested array
Hi to everyone.. now i have a little problem counting an nested array. Im using it to fill a Java TreeView... it looks like this: [1] => Array ( [1] => Array ( [1] => Array ( [1] => LECHE PREMIUM 1 LT [2] => LECHE PREMIUM 1/2 GL [3] => LECHE PREMIUM 1 GL ) [2] => Array ( [1] => LECHE LIGHT 1 LT [2] => LECHE LIGHT 1/2 GL [3] => LECHE FRESCA 1 GL LIGHT ) [3] => Array ( [1] => LECHE SEMI 1 LT FRESCA [2] => LECHE DESLACTOSADA 21 DIAS 1 LT [3] => LECHE SILUETTE 21 DIAS 1 LT [4] => LECHE DESARROLLO 21 DIAS 1 LT [5] => LECHE ENTERA 21 DIAS 1 LT [6] => LECHE LIGHT 21 DIAS 1 LT ) [5] => Array ( [1] => LECHE FRESCA 1 GL SEMIDESCREMADA BELL [2] => LECHE FRESCA 1/2 GL SEMIDESCREMADA BELL ) [6] => Array ( [1] => LECHE FRESCA 1 GL LIGHT BELL [2] => LECHE FRESCA 1/2 GL LIGHT BELL [3] => LECHE FRESCA 1 LT LIGHT BELL ) [7] => Array ( [1] => LECHE FRESCA 1 GL ENTERA BELL [2] => LECHE FRESCA 1/2 GL ENTERA BELL [3] => LECHE FRESCA 1LT ENTERA BELL ) ) The number of the branches is not always the same.. (it depends on the query).. when i use count($array, COUNT_RECURSIVE) for nested arrays.. it give to me the total including the nodes in the branches ( in this case 28).. now here is the question, how i can get only the last nodes in this case ... exist a easy way to do it?. or its necessary to make a funcion with a bunch of foreach?.. any suggestions are welcome =o) thanks! -- JOSUE ARANDA>>> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
